Many Cowboys fans would like a fresh start themselves after their team traded down 13 spots to select Frederick with the 31st pick Thursday night. In making the 60th draft-day trade of the Jerry Jones era, Dallas passed over several more heralded players at positions of need to take an underclassman given a third-round grade by some analysts.

“If the rest of the draft goes like this, we will have a top-five pick next year and be looking for a new head coach,” a fan identified as Donnie told Dallas radio station KRLD-FM. “It's very sad we have to put up with this mediocrity all the time.”

Referring to Jones, a fan identified as Jay from Fort Worth said, “I wish he'd sell this team and get the hell out of Texas.”

Jones is taking a beating because it was a reach to take Frederick in the first round. Dallas should have stayed put and selected from a group that included defensive tackles Sharrif Floyd and Sylvester Williams, safety Eric Reid and guard Justin Pugh and then grabbed Frederick in the third round.

But Jones believes the Cowboys gained value by also picking up another third-round pick (No. 74) in the trade with the 49ers and fulfilled their goal of fortifying the offensive line. Dallas placed first-round grades on 19 players, and Frederick was 22nd on its board, a higher grade than the one assigned to Pugh.

“Bottom line, we were very true to the grading of our scouts and very true to what we were trying to accomplish,” Jones said.

Fair enough. But that doesn't mean the club accurately evaluated Frederick or put together the right board.

NFL Network analyst and former Ravens coach Brian Billick said on Twitter you can't go wrong taking a Wisconsin offensive lineman. But the Cowboys should know that's not true.

Frederick is the third center from Wisconsin drafted by Dallas in the past 11 years. The other two — Al Johnson taken in the second round in 2003, and Bill Nagy selected in the seventh round in 2011 — couldn't shake the injury bug and lasted only three and one seasons, respectively, in Dallas.

Then there are Frederick's measurables. He posted subpar efforts in the 40-yard dash and bench press at the combine and his school's pro day. But the biggest concern should be what scouts say about him.

Even DallasCowboys.com's Bryan Broaddus, a former NFL scout, gave him a negative review.

“Doesn't play with much pop,” Broaddus wrote in a pull-no-punches report.

On the plus side, Frederick was the No. 1 center in the draft, and teammates at Wisconsin described him as a “brainiac” who rarely made a bad line call.

“I play with a high football IQ,” said Frederick, who has a chemical engineering degree.

Time will tell whether Jones made the right decision. But should Frederick falter while, say, Pugh shines for the Giants, who took the Syracuse product 19th, or while Floyd stars for the Vikings, who took the Florida alum with the 23rd pick?

Well, if those scenarios play out, Jones might want to grow his own beard and try for once to keep a low profile.
